  Exploring the separation mechanism of Gemini surfactant in scheelite ...

  2023115 · Highlights • In the range of 0 °C to 25 °C, HDDA has a stronger collecting ability to scheelite than DDA. • HDDA exhibited excellent selectivity for calcite even at 0 °C. • No chemical interactions between HDDA molecules and scheelite or calcite clusters. • The interaction of Gemini surfactant on scheelite surface is electrostatic adsorption.

  Flotation separation of scheelite from calcite using luteolin …

  202444 · This paper proposes luteolin (LUT) as a novel depressant for the flotation-based separation of scheelite and calcite in a sodium oleate (NaOL) system. The suitability of LUT as a calcite depressant is confirmed through micro-flotation testing. At pH = 9, with LUT concentration of 50 mg·L−1 and NaOL concentration of 50 mg·L−1, scheelite …

  Separators: a review of uses and limitations | Orthodontic …

  2018112 · Abstract: Orthodontic separators (commonly known as spacers) are elastomeric or metal auxiliary appliances, which are often used in Orthodontics to create space between teeth and allow fitting of an orthodontic band. Separators can also be used to create space for other reasons such as to facilitate interdental reduction.

  2016125 · The analyses of FTIR spectra, zeta potential and XPS illustrated that besides the electrostatic attraction with Ca cationic species on scheelite surfaces, NHOD might chemisorb onto scheelite by formation of NHOD-W surface complexes, resulting in a superior selectivity to scheelite compared with calcite.

  Texture and geochemistry of multi-stage hydrothermal scheelite …

  202061 · Our work shows that scheelite geochemistry can be used to trace the mineralizing conditions but the compositions may be significantly modified during the ore-forming process. Thus, detailed textural relationships should be investigated before using scheelite geochemistry to constrain the hydrothermal fluids and ore genesis.
